[ https://issues.apache.org/jira/browse/LUCENE-2556?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Adriano Crestani updated LUCENE-2556: - Attachment: lucene_2556_adriano_crestani_07_23_2010.patch This patch optimizes the cloning of the CharTermAttributeImpl internal buffer. It keeps using clone() to clone the internal buffer when CharTermAttribute.length() is at least 150 and at least 75% and of the internal buffer length, otherwise, it uses System.arrayCopy(...) to clone it using CharTermAttribute.length() as the new internal buffer size. It's performing the optimization, because in some scenarios, like cloning long arrays, clone() is usually faster than System.arrayCopy(...).
